BENJAMIN F. LEWVIS, OF AMESBURY, MASSACHUSETTS.

SHAFT-SHACKLE.

SPECIFICATION forming part of Letters Patent No. 314,694, dated March 31, 1885.

Application filed October 13,1584.

To all whom it may concern.

Be it known that I, BENJAMIN F. LEwIs, of Amesbury, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement'in Shifting Shaft-Shackles, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claim.

This invention has for its object the production of a shaft-shackle for vehicles which facilitates the disconnecting of the shafts from the'vehicle without disturbance of the pivotbolt of the shackle or the liberation of the compressed anti-rattler cushion; and it will, in connection with the drawings, be hereinafter fully described and claimed.

In said drawings, Figure l is an elevation showing my invention in connection with the shaft, axle, and shackle. Fig. 2 is a View similar to Fig. 1, except that the axle, the shackle, and thelower portion of the shaft are shown in vertical section taken on a line pass ing centrally through the shaft. Fig. 3 is a top or plan View of Fig. 1; and Fig. 4: is a view like Fig. 1, but showing certain modifr cations.

In said views, A represents the axle, Bis

the shaft, and Gthe wooden stock, all of usual eye h is secured between ears I), in the wellknown manner.

Instead of forming the under iron, (2, of the shafts with eye 71 at its rear extremity adapted to receive pivot-bolt c, I form thereon the eye 9, having a rectangular hole or passage, as

shown, to receive the strap a, which is inte- (X0 model.)

gral with and extends from eye h, and is arranged upon the upper side of shaft B, to

which it is secured by said eyeg and the screwbolt 6, which passes through iron. d, the shaft, and strap i, shown.

Instead of securing the strap 13 to the shaft by one bolt 0, as shown in Figs I, 2, 3, two of said bolts may be employed, as shown in Fig. 4; and, if desired, ashoulder, m, may be formed on strap t" and arranged to bear against eye g, as shown in said Fig. 4. By thus forming the iron d with an eye adapted to receive strap i, and forming said strapt integral with the pivotal eye IL and securing it upon the upper side of the shaft by means of eye 9 and bolt 0, the end of the shaft is secured between strapsd and 2',- and when it is desired to detach the shafts from the carriage, either to replace them with a pole or for other reasons, it is only necessary to remove the screw'nuts from bolts 6 and drift the bolts below straps t, when the shafts may be instantly detached from the vehicle, leaving strapsz with their pivotal eyes It still m0unted upon bolts 0, and with the pressure of buffers j 7: still exerted thereon; and the shafts or a pole may be attached to the vehicle as readily as the shafts are detached therefrom.

I claim as n'1y invention The strap t, formed to be attached to th part of the shackle secured to the axle and to extend along the top of shaft B, in combination with strap d, formed with eye g, to receive strap 1', and curved upward a distance sufficient to admit the shaft between said straps, substantially as specified.
